Frank H. Knight was one of the founders of the so-called Chicago school of economics, of which milton friedman and george stigler were the leading members from the 1950s to the 1980s. Knight made his reputation with his book Risk, Uncertainty, and Profit, which was based on his Ph.D. dissertation. In it Knight set out […]| Econlib
Milton Friedman was the twentieth century’s most prominent advocate of free markets. Born in 1912 to Jewish immigrants in New York City, he attended Rutgers University, where he earned his B.A. at the age of twenty. He went on to earn his M.A. from the University of Chicago in 1933 and his Ph.D. from […]| Econlib

Indeed, as can be seen in Figure 1, investment has dropped sharply during almost every postwar U.S. recession. As the graph suggests, one cannot […]| Econlib
On the topic of international trade, the views of economists tend to differ from those of the general public. There are three principal differences. First, many noneconomists believe that it is more advantageous to trade with other members of one’s nation or ethnic group than with outsiders. Economists see all forms of trade as equally […]| Econlib
George Stigler was the quintessential empirical economist. Paging through his classic microeconomics text The Theory of Price, one is struck by how many principles of economics are illustrated with real data rather than hypothetical examples. Stigler deserves a great deal of the credit for getting economists to look at data and evidence. Stigler’s two longest-held […]| Econlib
